This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Web blight of common beans caused by Rhizoctonia solani is a very important disease in bean growing regions of Latin America and the Caribbean. There are no cultivars with high levels of resistance available mostly because of a lack of information on the pathogen genetic diversity and virulence patterns and the need to find sources of resistance that can be introgressed into common bean. To study virulence patterns, the development of a set of differential bean lines is essential. Two groups of candidate bean lines were screened with isolates from AG 1-1F, AG 1-1E and AG 1-1A using the detached leaf technique. No significant differences were found among lines at any of the different growing conditions tested. All lines were rated as susceptible to all isolates even though they were selected based on the moderate resistance they showed in field trials. Thus new screening methods and more cultivars/lines need to be studied in order to develop a set of differentials. Genetic diversity of isolates collected in Puerto Rico, Honduras and the Dominican Republic over ten years from the two newly described subgroups AG 1-1E and AG 1-1F was assayed with four molecular markers. While some isolates were found to be clonal, Universal Rice Primers (URP) markers were the most informative showing differences between countries and years of collection for most of the isolates. This would support the hypothesis that population structure has changed over time and that there could be sexual recombination among a few genotypes. A group of 71 accessions from several species of Phaseolus including wild and landrace collections was tested for resistance to isolates from AG 1-1F, AG 1-1E and AG 1-1F. Fifteen lines were classified as moderately resistant to AG 1-1A but susceptible to the other two subgroups. Line 01-006-3B from P. coccineus was found to be resistant to AG 1-1F, intermediate to AG 1-1E and susceptible to AG 1-1A making it the best line to be considered for common bean breeding.

Download or read book Rhizoctonia Species Taxonomy Molecular Biology Ecology Pathology and Disease Control written by B. Sneh and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rhizoctonia Species: Taxonomy, Molecular Biology, Ecology, Pathology and Control, written by the world's most reputable experts in their respective fields of Rhizoctonia research, summarizes years of research in the various aspects of the ubiquitous complex group of soil-borne fungi belonging to the anamorph genus Rhizoctonia. Species of Rhizoctonia worldwide cause economically important diseases on most of the world's important plants such as cereals, potato, cotton, sugarbeet, vegetables, ornamentals and trees in nurseries. The subject reviews covered in the book include classic as well as modern approaches to Rhizoctonia research in: Taxonomy and Evolution, Genetics and Pathogenicity, Plant-Rhizoctonia Interactions, Ecology, Population and Disease Dynamics, Disease Occurrence and Management in Various Crops, Cultural Control, Biological Control, Germplasm for Resistance, Chemical and Integrated Control Strategies. It aims to be the standard reference source book on Rhizoctonia for the next decade or more, just as Parmeter et al. (1970) has been in the past. It will be an important publication for Rhizoctonia investigators, plant pathologists, students, extension specialists, crop producers and companies dealing with plant disease control.

This book was released on 1960 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Handbook supersedes Department bulletin 1366, "A check list of diseases of economic plants in the United States," issued in 1926. It replaces the processed report, "Index of Plant Diseases in the United States," issued in six parts, from 1950 to 1953. The Handbook does not constitute a revision of the "Index," issued from 1950 to 1953. There are no real changes in content. Condensation of the introductory explanation, and some minor changes, mainly in the host descriptions, to permit better arrangement of the printed page, are the most conspicuous differences from the original "Index."
